Compressed Air and Cutting Fluid in Lathe Milling Drilling Machine for Cooling System

Abstract

While cutting operation, high temperature is produced. that high temperature often leads to several problems like a high heat affected zone, temperature tool wear, change in hardness and micro-structure of the work piece, burning and its consequence and micro cracks. Application of cutting fluids in conventional method reduces the above problems to some extent through cooling and lubricating of the cutting zone. But in this process the cooling rate is low. For this reason, mist application technique has become the focus of attention of researchers and technicians in the field of machining as an alternative to traditional flood cooling. The minimization of the requirement of cutting fluids leads to economical benefits, and environmental friendly machining This paper deals with some studies of mist application that is compressed air with fluid for cutting operation on milling machine. For this, a mist generator set-up was developed. A series of machining operation have been conducted under various mist application condition for find out the effect on the performance of the mist applicator. The optimum quantity of cutting fluid required to maintain the cutting zone temperature beyond 35⁰C at various cutting conditions is determined. The optimization of cutting fluid bring the most economical condition for cutting fluid usage.
